Flat Vapor Chamber (VC for short) is a heat dissipation device with capillary structure on the inner wall. When heat is conducted from heat source to evaporation zone, the working medium in the chamber will vaporize and absorb heat. The vapor working medium will condense and release heat in the low temperature zone inside the heat pipe, and the liquid working medium after condensation will return to the heat source under the action of capillary force or gravity. Thus, the rapid diffusion and transfer of heat can be achieved.
In practical application, the real performance depends on the welding method, preparation of capillary structure, selection of working medium, cavity configuration and actual heat transfer path and other factors.
